To all whom it may concern,.-

Beit known that I, FRED H. DANIELs, a citizen of the United States,I residing at Worcester, county ofWorcester, State of Massachusetts, have invented certain new and useful provements in Apparatus for Treating Wire'Rods; and I do hereby declare the following to be a full, clean, and exact description of the invention, such as will enableAv others skilled in the art to which it appertains to make and use the same.

' My invention relates to the manufacture of wire rods, .and more particularly consists in improved means for cooling the sameA and preventing the formation of scale thereon as they come from the nishing mill. The wire rods, as they come hot from the mill, are coiled or reeled,. and, in. order to revent `too heavy scale formi-ngwhile' the coi is 'cooling inthe open airy'it'has heretofore been the custom, insome ca`S`eS,- to cool them by .immersing them in water immediately after the coiling operation. This operation, however, seemstoo violent' for the highly `heatedrods, andresults inchilling and hardening them to an injurious degree, and i`t is thel urpose of this. invention fto eii'ect the cooling by a milder process that may either be employed -as preliminary to the usual immersion, or

maybe the only cooling to which they are subjected.

In United yStates Patent No. 737,361,

granted to me August 25, 1903 I showed,

`described and claimed an apparatus for coiling the rods in a practically air-tight casing containing steam or a non-oxidizing gas, and lpassing the completed coils slowly through a continuation of said casing from which they were finally. deliveredy into awaterbath.

This apparatus effectively prevents the formation of acoating of o xid of iron upon the. rods, and the object ofthe present invention is to obtain the same general results in substantially the same way, whilel coiling the creating 'aroun siiformed, the water being divided up into mirods in the open air and v'vithout'inclosing the -coiler or. the Wire .in the casing, though4 I would have' it understood that the present aparatus may be inclosed ifdesired.

jenerically speaking, the operation performed by the resent'fa paratus consists in the ro during the olperation of coiling, a non-oxidizing atmosp of steam .and finely-divided moisture by vspraying. the coil with water as itis being .nuto particles by the relative rotary moves .my improved cooling and sca .means;

`tated by the bevel ere ment between the spraying nozzles and parts of the coiler. p

The mechanism by which this4 operation may be carried out, as well `as further details ofthe operationandof the-advantages secured by their use' -will -be apparent'from the following detailed description, taken in con-- nection 'with the. accompanying. three sheets of drawings, in which:

Figure 1 is a frontelevation, partV being` shown in section, of a coiling plant havin a capacity of four reels and ezliuipped with Fig..2 is -a cross sectionof Fig. 1',

taken on the line thereof; Fig. 3 is a side elevation of the automatic coiler, partly in i section, and of the spraying mechanism, also e preventing partly in section, and Fig.- 4 is a plan view of the spraylng mechanism. Referring particularly first to Fig. 3 of the drawings, the finished wire mis delivered through the pipe f @to the rotating tubular arm b of the automatic coiler t, which may be of usual construction, -said arm be;A g rogears af a. Thel rod is thus wound in a coil upon the inclined platform d, through which `projectpegs or pins c, `which are adaptedto .be retracted -by lever mechanism le `and handle n, `which `may be constructed in any usual way and which will ge clearly understood from n inspection of When the o il or bundle y is 'com pins c are withdrawn and the bun le y slides by gravityofi said platform onto a suitablesupporting surface, which may, as shown, be a conveyero, running a tan r or water bath 1aed, uitA m for fin l1 cooling the rod so'that it can be handled, ter having been, by means of the spraying process described above, cooled to a temperature below the critical point at which the metal v may be `hardened or tempered.

This final cooling ma or may not be used,

and the coil may be elivered to a conveyor or stationary latform without the addition of a'water tanlri). r c 'From a suitably located reservoir Z vorlos` other source I extend a systemof piping gif/1,

whlch communicates with hollow supply heads g, one of said supply heads being lo cated adjacent to, and partially.. encircling cache-collar b'. Toeach of said heads are secured a lplurality of atomizer n'oiizlesh, three 4being s own in the drawlng, which are lo- I'Io cated so as t'o direct the sprays issuing from them upon the 'rods as they are wound,`by

the coiler t, around the pins c on the platform d.

The ends of the atomizers h are provided with small apertures h and the water is caused to issue therefrom with considerable force in a fine spray by means of air, steam or other gaseous'iiuid under pressure delivered from a'reservoir "i, through pipes 0'/ to a nozzle axially located within each ,atome izer L. A. needle valve 2, at the upper end of'each nozzle controls the pressure in each atomizer. The pipes f through 'which the rod @c is vfed to the coiler and the coiler arm b may also he utilized as a waterl passage. I' have shown a branch pipe e, provided with -a .cock e', and leading into the pipe. f for this purpose. I do lnot con-fine myself to a nozzle constructed according to the above description; any suitable spraying-nozzle may be used.

The operation will now be described. The

wire as it 4comes' trom the rolls is guided 4by :the pipe f into-the coiler and by the latter is laid around the pins c. The water issuing in ne sprays from the atomizers h is still more 4'finely divided by the impact of therevolving arm b and the Wire issuing therefrom. As vsoon .as a sufficient number of turns of Wire have been coiled around the pins c, .thecock e -is opened admitting water. to thepipe and revolving varm b, and as said Water .issues from the end of said arm, it

mingles with #the sprays from the atomizers 7i, the result being -ito spray or atomize still further .the Water comingfrom both sources.

As the water, in this iinely-divided condition,

strikes the vhot wire in the coil, steam is formed, which, coupled with the iine mist pervading the entire Vplatform d, .effectually prevents the oxidation of the wire .while at the same time'cooling the same suiiiciently gradually to prevent a chilling or hardening action. lVhen .the coil is completed, thel vpins c are withdrawn and .the .coil slides oli the platform d preferably into the bath m .and onto the conveyer o.

It is to be noted that the water issuing from the revolving arm bstrikes the coil and the .platform on which it is being formed with considerable force, and is broken up into minute particles similar .to those issuing from the spray nozzles or atomizers h. This action is greatly facilitated by the rotation of the arm b', causing the jets to strike the pins c, the coil itself, and other parts of the apparatus, which, though actually stationary, are relatively movable with respect to the Water which is thus projected upon them, and cause the fine stream of Water to rebound and be further broken up so as to be the more easily converted into steam by the heat of the coil.

What lf claim is 1. An apparatus for treating Wire rods, comprising a stationary reel, a spraying mechanism arranged to create an atmosphere of finely divided water spray in prox- -imity to the reel, and a revolving coiler arranged to pass the wire through the spray on its way to the reel.

2. An apparatus for treating wire rods, comprising a hollow revolving coiler arranged to receive the Wire as it comes from the iinishing mill, a relatively stationary reel, atomizers to deliver a finely-divided spray upon said reel, and a pipe to force water through said coiler along with the wire.

3. An apparatus for treating wire-rods, comprising a hollow, revolving coiler arm arranged to receive the wire as it comes from .the iinishing mill, and a pipe to force water 4under pressure through said coiler arm,

whereby a stream of water will be caused to issue from said arm with the wire.

4. An apparatus for treating wire rods., comprising a hollow, revolving coiler arm arranged tol receive the wire as it comes from -the finishing mill, means arranged to convey Water into and through said coiler arm, and atomiz'ers to project a finely divided spray or mist onto said wire during the c'oiling process, said .atomizers being located at intervals in a circle approximating that described by the coiler.

'In testimony whereof I aiiix my signature, in presence of two witnesses.
